General Assembly, some memorable for their accomplishments, others for their political views, allegations against them, and the reputations of the countries they represent. The arrest of the 68th president, John Ashe of Antigua, in an alleged bribery case has put the spotlight on the presidency of the 193-member world body, which rotates every year by region.
